Saluran distribusi berperan dalam aktivitas logistik dari suatu produk pangan. Dalam tinjauan halal, aktivitas logistik erat kaitannya dengan status kehalalan pangan. Kehalalan pangan tidak hanya bergantung pada bahan baku yang digunakan, tetapi juga jaminan bebas kontaminasi dari bahan yang diharamkan sepanjang aliran produk dari titik asal produk hingga ke titik tempat dikonsumsinya produk. Penelitian ini bertujuan mengetahui saluran distribusi dari produk pangan jajanan anak sekolah berbasis olahan daging berupa bakso, sosis, dan cireng isi daging di wilayah Bogor yang ditinjau dari perspektif kehalalan logistik. Metode yang digunakan dalam penelitian ini adalah dengan wawancara menggunakan alat bantu kuesioner. Penentuan sampel dilakukan secara purposive sampling. Berdasarkan hasil penelitian, saluran distribusi yang digunakan pada pemasaran bakso, sosis, dan cireng isi daging berturut-turut adalah zero-level channel, three-level channel, dan four-level channel. Semakin panjang saluran distribusi, semakin banyak aktivitas logistik yang dilakukan, dan semakin besar potensi kontaminasi produk halal dengan bahan yang nonhalal.KATA KUNCI: level, logistik, halal, pemasaran, bakso, sosis, cireng isi daging; level, logistic, halal, marketing, meatball, sausage, fried tapioca-filled-with-meat DISTRIBUTION CHANNEL OF MEAT BASED SNACK THAT IS CONSUMED BY SCHOOL STUDENTSABSTRACTDistribution channels play role in logistic activity of food product. In halal perspective, distribution channels have a strong relation with halalness of food product. The halalness of food product does not only depend on the origin of material but also guarantee of non-halal material free contamination during the product flow from point of product origin to point of product to be consumed. The aim of this research was to define the distribution channel of snack that is consumed by school students in Bogor city including meatball, sausage, and fried tapioca-filled-with-meat related to halal logistic perspective. The method of this research was by interview using questionnaire. Sampling method was by purposive sampling. Based on the result, the distribution channels in meatballs marketing, sausage marketing, and fried tapioca-filled-with-meat marketing were zero-level channel, three-level channel, and four-level channels, respectively. A longer distribution channel makes a greater number of logistic activities and it has a bigger potency of contamination of non-halal material to the halal product.

Pewarna alami lebih disukai karena tidak memiliki efek yang negatif terhadap tubuh manusia sehingga mempunyai tingkat keamanan pangan yang tinggi, selain itu juga pewarna alami mudah diuraikan. Bahan pewarna alami bisa diperoleh dari berbagai jenis sumber, salah satunya yaitu spesies alga yang merupakan tumbuhan tingkat rendah di perairan. Alga terdapat 2 jenis yaitu makroalga yang berukuran besar dan mikroalga yang berukuran kecil (renik). Spesies mikroalga yang dapat menghasilkan pewarna alami salah satunya adalah Spirulina. Jenis pewarna alami yang terkandung pada mikroalga tersebut yaitu fikosianin. Pada penelitian ini, dilakukan ekstraksi fikosianin dari Spirulina platensis dengan menggunakan tiga metode berbeda yaitu Maserasi, Ultrasound-Assisted-Extraction (UAE) dan Freezing untuk mengetahui metode mana untuk menghasilkan yield dan antioksidan tertinggi dari ekstrak yang dihasilkan. Hasil dari penelitian ini didapatkan bahwa berdasarkan nilai yield tertinggi dan kandungan fikosianin, freezing merupakan metode ekstraksi terbaik dengan kandungan fikosianin yang paling tinggi yaitu sebesar 26,53%. Sedangkan nilai aktivitas antioksidan terbesar dihasilkan oleh metode ekstraksi maserasi dengan nilai IC50 sebesar 49,59 ppm. Fikosianin yang dihasilkan dari ketiga metode ekstraksi termasuk antioksidan kuat.KATA KUNCI: ekstraksi, Spirulina plantesis, fikosianin, biopigmen, antioksidanEXTRACTION OF PHYCOCYANIN FROM SPIRULINA PLANTESIS FOR BIOPIGMENT AND ANTIOXIDANTABSTRACTRecently, biopigment known as a pigment which has no impact and easy to degradated in human body and better than artificial pigment. Biopigment can be resulted from the extraction of algae that are living in the water. Spirulina plantesis is one of algae resulting a pigment and known as phycocyanin. In this research, extraction of phycocyanin was done by three method of extractions; maceration, Ultrasound-Assisted-Extraction (UAE) and Freeze-thaw. Those extraction methods were compared to decide which method that resulted highest yield of extraction and has highest antioxidant activities. From the resulted data, the highest yield and highest phycocyanin concentration was obtained by freeze-thaw extraction method. Phycocyanin concentration from freeze-thaw ectract was 26,53% (w/w). However, the highest antioxidant activities was obtained by maceraion extraction mehod. The IC50 of extract from maceration was 49,59 ppm. Hence, all extracts from different extraction methods resulted high antioxidant activities.
